The honest version

WHAT IS
ACTUALLY KNOWN

We would rather you bought with your eyes open than not at all. Here is the state of the evidence, including the parts that do not help us.

01

What it is

This is a steroidal compound often grouped with SARMs. Structurally a steroid, not a true SARM. Sometimes described as a myostatin-pathway agent.

02

State of the evidence

The myostatin description rests largely on a single cell-culture study. There is no human data.

03

Known risks

A steroidal structure means androgenic and liver effects cannot be ruled out.

04

Regulatory status

Not authorised for human consumption in the UK or EU.

05

Status in sport

Prohibited in sport by WADA.

06

What we verify

Identity and purity, per batch, by a laboratory we do not own. We verify what is in the capsule — nothing about what it does.

WHAT WE CAN
PROVE

We don't have customer reviews to show you yet, and we're not going to invent any. Here is what we can actually put in front of you instead.

Assayed by a lab we don't own

Batches go to Janoshik Analytical, an independent testing laboratory. We don't choose the result.

Tested per batch, not per year

A certificate from a batch made two years ago says nothing about the pack in your hand.

Batch number on the pack

Email it to us with the product name and we'll send the Certificate of Analysis for that batch.

Good to know

QUESTIONS, ANSWERED

Structurally a steroid, not a true SARM. Sometimes described as a myostatin-pathway agent. The myostatin description rests largely on a single cell-culture study. There is no human data.

This product is supplied for laboratory research use only. We do not provide dosing instructions, cycle lengths or post-cycle protocols for human use.

We do not give post-cycle therapy advice. This is a question for a qualified clinician, not for a shop.

Not strictly. It has a steroidal backbone, which is why grouping it with selective androgen receptor modulators is misleading. We would rather describe it accurately than conveniently.

Yes — identity and purity, per batch, by Janoshik Analytical. Email us the batch number from your pack and we will send that batch's Certificate of Analysis. You do not need to have bought anything to ask.
